Phoenix Fall ID: Pitching Data Dive

On Sunday, October 29th, the PBR Arizona staff hosted the Phoenix Fall ID at Brazell Field at GCU Ballpark in Phoenix, Arizona. This event featured 53 prospects from the 2024 - 2027 classes and allowed our staff an opportunity to get an in-depth look and analysis of the players in attendance.

Earlier this week, we broke down the top measurable data performers from the event with our Statistical Analysis article. Now, we will take a further in-depth look at the top pitchers with the help of our tech partnerships, broken down by the categories down below:

FASTBALL

MAX VELOCITY (MPH)

Rank Name State School Class Pos Velocity (max)
1 Greg Mattison AZ Canyon View 2024 RHP 88.3 mph
2 Ashton Higgins AZ Notre Dame Prep 2025 RHP 88.1 mph
3 Devin Morganfield AZ Valley Christian 2026 RHP 85.9 mph
4 Landon Hood AZ Canyon View 2025 RHP 85.7 mph
5 Brock MacDonald AZ Desert Vista 2026 RHP 85.6 mph
6 Tanner Thornton AZ Flowing Wells 2024 OF 83.5 mph
7 Henry Verhamme AZ Cactus Shadows 2026 SS 83.4 mph
8 Trey Parker AZ Coconino 2026 OF 82.5 mph
9 Noah Pringle AZ Liberty 2025 1B 81.0 mph
10 Dylan Keith AZ Red Mountain 2027 OF 81.0 mph

Max Fastball Velocity: This metric calculates the speed of the pitch as it’s released from the pitcher’s hand.

SPIN RATE (AVG)

Rank Name State School Class Pos Spin Rate (avg)
1 Brock MacDonald AZ Desert Vista 2026 RHP 2411 rpm
2 Greg Mattison AZ Canyon View 2024 RHP 2257 rpm
3 Landon Hood AZ Canyon View 2025 RHP 2243 rpm
4 Tanner Thornton AZ Flowing Wells 2024 OF 2058 rpm
5 Andrew Bromley AZ Desert Ridge 2025 RHP 2044 rpm

Spin Rate: This metric calculates the rate of spin on the baseball as it leaves the pitcher’s hand, measured in revolutions per minute (rpm). Historical data shows that high-spin fastballs lessen the impact of gravity, allowing for more ‘rise’ (or less fall, in other words) as it carries through the zone. Low-spin fastballs typically indicate the pitch has greater horizontal action, often making it tougher to square up, but generally easier to make contact with, leading to more ground balls, while high-spin fastballs show a correlation with swings and misses.

INDUCED VERTICAL BREAK (AVG.)

Rank Name State School Class Pos IVB (avg)
1 Landon Hood AZ Canyon View 2025 RHP 17.3 in
2 Greg Mattison AZ Canyon View 2024 RHP 17.1 in
3 Sam Sejong Hwang AZ Desert Vista High School 2027 RHP 16.6 in
4 Tanner Thornton AZ Flowing Wells 2024 OF 16.5 in
5 Henry Verhamme AZ Cactus Shadows 2026 SS 16.5 in

Induced Vertical Break: Used in short form as "IVB," this metric is most important on fastballs for creating rise and on curveballs for creating depth – it can also have some use when measuring sliders and cutters as well. Sliders tend to be closer to zero inches while cutters are generally between 5 and 15 inches. Usually fastballs and curveballs with large IVB have higher spin efficiencies as well. Sliders generally have very little (closer to zero) IVB and very low spin efficiency. You could also categorize IVB into spin rate as this is part of the “useful movement” you’re looking for. IVB is also a huge part of the vertical approach angle.

HORIZONTAL MOVEMENT (AVG.)

Rank Name State School Class Pos HM (avg)
1 Noah Pringle AZ Liberty 2025 1B -13.3
2 Dylan Keith AZ Red Mountain 2027 OF 12.3
3 Andrew Bromley AZ Desert Ridge 2025 RHP 11.4
4 Tytin Clancy AZ Queen Creek 2027 2B 10.4
5 Devin Morganfield AZ Valley Christian 2026 RHP 10.3

Horizontal Break: Outlined on TrackMan’s own website: “... horizontal movement is measured in inches between where the pitch actually crosses the front of home plate side-wise, and where it would have crossed home plate side-wise if had it traveled in a perfectly straight line from release. A positive number means the break was to the right from the pitcher’s perspective, while a negative number means the break was to the left from the pitcher’s perspective.”
